    摘要： An assist gas fuel injection mechanism for a 2-cycle internal combustion engine includes a chamber communicated to a combustion chamber through a communicating passage. A rotary valve is provided in the communicating passage for controlling the opening and closing of the communicating passage. A fuel injection device is provided in the communicating passage between the rotary valve and the chamber. With this configuration, a highly compressed gas from the chamber, and fuel from the fuel injection device, are mixed with each other, and a concentrated mixture gas is supplied to the combustion chamber through the communicating passage. A protective layer is provided on the outside surface of the valve body of the rotary valve by using a material which is softer than the valve body of the rotary valve and the housing of the rotary valve and which is susceptible to plastic deformation.

    摘要： A control valve is disposed in a communication passage for communication between a combustion chamber and a chamber portion adjacent to the combustion chamber, and through the communication passage at least one of a fuel and an air-fuel mixture, and a highly compressed gas, are supplied or charged into the combustion chamber and the chamber portion adjacent thereto, respectively. The control valve includes a first control valve disposed in the first communication passage and a second control valve disposed in the second communication passage, the first control valve causes the first communication passage to open at a timing near closing of an exhaust port and causes it to close halfway in a compression stroke. The second control valve causes the second communication passage to open at a timing near closing of the scavenging ports and causes it to close prior to closing of the first communication passage.

    摘要： A two-cycle internal combustion engine includes a control valve disposed within a communicating passage between the combustion chamber and a chamber portion adjacent to the combustion chamber. The control valve is for controlling the opening and closing of the communicating passage. Blowby of an air-fuel mixture supplied to the combustion chamber can be prevented to reduce fuel consumption and increase the exhaust gas purifying performance. A communicating passage portion between the control valve and the fuel supply opening is configured to spray fuel from the control valve to a part or all of a wall surface of the communicating passage portion and the wall surface of the communicating passage portion is shaped to guide the fuel into the combustion chamber.

    摘要： A deceleration control apparatus is provided which can control a two-cycle engine of the spark ignition type for a vehicle, in which fresh air in a combustion chamber can be self-ignited at an ignition timing preferable for operation of the engine at least upon low load operation, so that, when engine sudden deceleration requirements are satisfied, the combustion condition is automatically changed over from an activated heat atmosphere combustion condition to an ordinary combustion condition to allow sudden deceleration of the engine. A sudden deceleration requirement discrimination CPU for discriminating requirements which require sudden deceleration of the vehicle receives, in addition to a detection signal from a throttle valve opening sensor, detection signals from a vehicle speed sensor, a kill switch, a main switch, a brake switch for detecting that the brakes are applied, a clutch switch for detecting that the clutch is disconnected, and a gear position switch for detecting that the shift operation position is operated to the neutral position, and when the requirements which require sudden deceleration are satisfied, the sudden deceleration requirement discrimination CPU sends an exhaust control valve opening correction signal to an exhaust control valve CPU.
